Understanding Azure

David GristwoodApplication Architect, Microsoft blogs.msdn.com/david_gristwood

Why a Cloud Platform?

Reduce capital & operations costs Simplify application deployment &

management Simplify scaling to internet scale Cost effectively handle peak loads Focus on new functionality & not

infrastructure

Azure is Live…..

The Azure Philosophy

Azure is about Scale

• Azure is designed from the ground up for true Internet scale

• Global presence• Ride the “network

effect”• LinkedIn: 16 months for first

million users, 11 days for most recent million

• Facebook: 5 years to hit 250m users, 8 months to double

• Scale up and scale down

• Supports the “Scale Fast, Fail Fast” model

Characteristics of Azure Applications

“Scale & Elasticity” • Need massive

scale• Need high

reliability• Have variable load• Have short or

unpredictable lifetime

Helps your Systems Scale

• Most architecture is hidden inside code

• Azure encourages you to define your application into constituent parts

• Azure can scale the parts of your application as appropriate

Flexible Architecture

• Systems evolve over time

• Cloud is not an “all or nothing” proposition

• Azure makes it easier to extend to the cloud

Opening up the Cloud

www.flickr.com/photos/h19/2306213399/in/set-72157594224557858

• Allow developers to apply their existing skills to the cloud

• Support for .NET, Ruby, PHP, Java

• Interoperability with any platform, tools or technology

Natural Platform Evolution

• Windows Server 2008

• Virtualisation• Windows

Services, such as IIS, logging, diagnostics, etc

• Visual Studio & .NET

Flexible Business Model

• No up front hardware purchase

• Pay as you go costing model

• Ideal in current economical climate

Provide simple interface for storing named files along with metadata for the file

Windows Azure Blob features REST based API

http://myaccount.blob.core.windows.net/mycontainer/myblob

PutBlob, GetBlob, DeleteBlob, CopyBlob, SnapshotBlob, LeaseBlob, etc

Block Blob for streaming + commit-based writes Sequence of blocks, size limit 200GB

per blob Page Blob for random read/write

Array of pages, size limit 1TB per blob




Windows Azure Drives Page Blob formatted as a NTFS single

volume Virtual Hard Drive (VHD) NTFS APIs providing durable file storage Drives can be up to 1TB, up to 16 can be

mounted Can upload VHD via Page Blob then

mount Ease migration of existing Windows

applications to Azure Durability and survival of data on

application failover or hardware failure

Windows Azure Tables

Structured storage via entities, containing sets of properties

Windows Azure Tables Provides Massively Scalable

Structured Storage Billions of entities (rows) and TBs of

data Familiar and Easy to use API

WCF Data Services, LINQ Each entity can have up to 255

properties PartitionKey & RowKey as key and index Timestamp for optimistic concurrency No fixed schema for all other properties Property is stored as a <name, typed

value> pair

Azure Features

Service Management APIProvide Lights-Out Service Management

Manage services programmatically via REST-based API X509 client certificates for authentication Viewing, creating, deleting, swapping,

modifying configuration settings, etc on deployments

Windows Azure Diagnostics

42

Cloud is much harder than single server Dynamic environment, no local access

Azure Diagnostics built for monitoring & data collection Focus on what to collect and when Designed for Azure

Based on standard APIs Traces, logs, crash dumps, IIS logs,

perf counters, ETW, etc Upload to Azure storage as required

Logging & Diagnostics

Service Management CmdLets

PowerShell cmdlets wrapping Azure Service Management and Diagnostics API

Simple to script out deployments, upgrades, scaling• Deploy new services• Upgrade services• Manage storage

accounts• Transfer diagnostics

information• etc

Service Upgrade Models Rolling upgrade (aka “In-

place”) Roles are updated across update

domains one at a time Service remains available during

upgrade Real-time hot swap (aka “VIP

Swap”) Virtual IP swap between staging &

production Swap service endpoints of

old/new version Enables complex architectural

changes Planned downtime

Stop and replace service with new version

Azure Content Delivery Network

Asia, Australia and South America) and growing

“SQL Server in the Cloud”“Database as a Service”

SQL Azure vs SQL Server

Similarities Scalable, reliable, robust, SQL Server

technology foundation Same SQL Server core database service Same TDS access

Differences Supports subset of SQL Server 2008 T-SQL Limited to 1Gb or 10Gb database Different pricing model No Reporting Services, Analysis Services, etc

Constants Constraints Cursors Index management and

rebuilding indexes Local temporary tables Reserved keywords Stored procedures Statistics management Transactions Triggers Tables, joins, and table

variables Transact-SQL language

o Create/drop databases

Information as a Service

54

Data or functionality that is “of value to many” – enabling applications, reports, BI analysis, etc… Examples include GIS/Spatial, traffic, movie show

times, crime, real-estate sales, financial data, navigation, census data, reviews, etc…

Various Classifications: Commercial: clean, supported, and regularly updated

from ISVs and Content Providers Trusted Public Domain: clean, unsupported data from

academia and governments (Census, FDA, …) Crowd Sourced: unreliable data in the public domain

from anyone and everyone

Services”) Service Bus Access Control

Service Bus

59

Exposing internal applications on the Internet isn’t easy

Network address translation (NAT) and firewalls get in the way

The Service Bus: Provides a cloud-based

intermediary between clients and internal applications

Provides a service registry that clients can use to find the services they need

Service Bus

60

Access Control

61

Different organizations identify users through many different techniques

Applications can be faced with a confusing mess of security related code

The Access Control Service: Implements a security token service

(STS) in the cloud It accepts one token and issues another An administrator can define rules for

how this claims transformation is done
